According to conspiracy theory channel, SecureTeam10, which obtained Bergrun's comments, the alien ships have been here for some time.
"Alien spacecraft are proliferating in our solar system and around these ringed planets," Bergrun is quoted as saying on the video.
Bergrun also noted the aircraft are by the other ringed-planets in the solar system, including Jupiter and Uranus.
Below is the video in its entirety:
SecureTeam 10, which has nearly 900,000 YouTube subscribers, often runs conspiracy theory-based videos. The organization describes itself as the "source for reporting the best in new UFO sighting news, info on the space cover-up, and the strange activity happening on and off of our planet."
Bergrun wrote the 1986 book entitled "Ringmakers of Saturn." The book highlights that there are massive alien ships around Saturn (which Bergrun dubs "ring makers"), including ones which have actually created some of the rings around the gas giant.
This is not the first time Bergrun has made comments like this, having done so previously in 2016.
